SGM8902 Capless 2Vrms to 3Vrms Line Driver with Adjustable Gain GENERAL DESCRIPTION The SGM8902 is a 2Vrms to 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced ponent count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters. The SGM8902 is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd-order low pass filter to pliment DAC's and SOC converters. The SGM8902 has build-in shutdown control for pop/click-free on/off control. Using the SGM8902 in audio products can reduce ponent count pared to traditional methods of generating a 2Vrms output. The SGM8902 doesn't require a power supply greater than 3.3V to generate a 5.6VPP output,...
